<p>A rotary drum type weft storage apparatus for a shuttleless weaving machine of the type wherein a weft yam (a) from a yarn supply source is wound up onto and stored on a rotatable yarn storage drum (9) comprises a holding drum (10) provided on the yarn withdrawal side of the yarn storage drum (9), a ring (22) loosely fitted on the outer periphery of the holding drum (10), a retaining member (19, 20) for retaining the ring (22), and a reciprocating driving mechanism (26,27,18) for moving the retaining member (19,20) back and forth to cause the ring (22) to be moved into and out of engagement with an enlarged diameter rib (14) on or adjacent to the holding drum (10). The weft yarn which passes over the rib (14), through the ring (22), and over the retaining member (19,20) is thus gripped and released in synchronism with the crankshaft of the weaving machine.</p> |
